<p><it>Abstract</it>—Paschalis et al. in [<ref rid="BIBC105512" type="bib">12</ref>] have given a structured method to design TSC <it>m</it>-out-of-2<it>m</it> code checkers suitable for VLSI implementation. In this correspondence we give sufficient conditions so that the method given in [<ref rid="BIBC105512" type="bib">12</ref>] can be used to design checkers for classes of <it>m</it>-out-of-<it>n</it> codes with <it>n</it>≠ 2<it>m</it>.</p>
